Parents need to know that there's not much room for debate in this show. The investigators are absolutely convinced that the alleged alien sightings they're studying are real and that they'll be able to find proof if they look hard enough. When their research is inconclusive (or completely fails to support their theories) they start to wonder about government conspiracies and hidden evidence but never consider the possibility that the incidents are anything but actual alien encounters. Viewers may certainly disagree, but those who do will find little reason to watch. All of that said, there's little obviously iffy content here -- a bit of bleeped swearing is about it.
Positive messages:The UFO investigators are searching for hard evidence of alien activity and are inclined to think that the authorities are all conspiring to hide the truth. They're also eternal optimists, and their repeated failures to find real evidence only makes them more convinced that the truth is still out there somewhere. They seem unwilling to accept the possibility that the incidents they're investigating may not actually involve extraterrestrials.
Violence:Some computer re-creations of flying saucers crashing.
